Problem cooling 2500k with Hyper 212 Plus - Page 2

post #11 of 27
Oh btw the cooler master hyper 212+ has crap contact with cpu compared to the evo. The 212+ has spacing in between the cooper pipes where the cpu is. The evo doesn't all the pipes are parallel to the cpu and have no spacing leading to better heat dissipation and better temps.

and also try to wiggle it, if it moves easily, then you are doing something wrong.

intel burn test isnt a good test to use yes it gets the cpu very hot but doesnt stress it as much as prime95 give prime a go and report back what temps you get with it

The cooler doesn't appear to be lopsided, but my CPU seems to be very slightly concave. It's good to hear that the temps might improve a little bit later on. I don't think I'll buy another cooler at this point; I'll deal with what I have and if I can't OC much or at all right now, oh well. If anything I'll wait until I have a bit more money and go for water cooling. The HSF doesn't wiggle, but I am able to turn it laterally a little bit (the amount of free space between the peg on the cooler and the sides of bracket holding it). I'll try out prime95 now.

Edit: Running blended torture tests using Prime95 at 3.8 GHz, I'm getting a max temp of 62 C on my third core and max package temp of 65. That's a bit lower than before. Will it really improve a little bit over the next week?

you will see a small increase with it not by much also adding another fan can help temps again by 2-5c but also i run my cpu @ around 78c and havnt had any issues, managed to get my 2600k to 4.5ghz with my old hyper212 and max temp was 75c

Alright then, so with a little time and a second fan I should see some improvement. Mid 70's at full load is pretty safe? It's not like I'll be running at that 24/7, but I'd like the CPU to last at least a couple of years. I'll use this machine mostly for gaming a few hours a day at most.

should be fine its hard to say because every cpu is different, ive only had my cpu for around 5months or so and still going very strong, also with gaming the temps wont get near as hot as prime and intel burn test gets em. i noticed while folding i hit around 78c (depending on the temp outside atm since summer is unpredictable here) but gaming wise it stays around 65c max

Alright then, that sounds good. I'll get a second fan and OC until I get into the mid 70s on Prime64 and then stick with that. Thanks everyone, for the help.

Your heatsink is resting on the edges of the ihs (integrated heat spreader). The cpu itself is in the center of the ihs. You need firm contact with the cpu, making the ihs a sandwich between the cpu and the 212+ contact plate.

 

Probably the best way to improve your temps at this point is to lap your cpu. BTW -- never lap an HDT heatsink like the 212+. HDT heatsinks already have their heapipes partially ground down to make them flat.

 

Another thing: the reason you get lower temps is that Prime95 does not stress the cpu as much as Linpack, the engine behind IBT. Prime95 is a better test of OC stability, but Linpack was designed by Intel to put the max thermal stress on cpu's, and that's just what I found. I use OCCT/Linpack to thermally stress my cpu for my various fan tests. You might get a somewhat lower average temp because the app rests between bouts, but its plateaus are the hottest.
